7 Claims. (Cl. 268119.)

The present invention relates to certain new and useful improvements in casement window constructions and has reference in particular to a novel construction whereby it becomes safely and conveniently possible to locate the exterior surface of a horizontally swinging casement window in a handy and reliable position for washing and cleaning said surface.

It is to be pointed out at this stage that the invention herein revealed is, of course, applicable to either double hung or single hung casement window constructions. For convenience, however, a single horizontally swinging casement Window is disclosed inasmuch as the structural novelty and principle of utilizing the same will, in this manner, be more easily comprehended and perhaps fully appreciated.

It is a matter of common knowledge that it is indeed a dreaded task to wash and clean the exterior surface of a casement window. For one to attempt to sit on a window sill and reach out in one way or another to wash the exterior surface of the pane or panes is, to say the least, wholly unsatisfactory and unsafe. Where the windows are high above the ground, the job often necessitates climbing a ladder poised against the outside of the building and here again great risks to safety are involved. It is manifest, therefore, that there has long existed a need for the construction of a casement window which permits the exterior surface to be swung toward the building in an are approaching one hundred and eighty degrees, more or less, so that said surface is then accessibly available for safe and handy washing accomplishments.

It follows that the present invention has for its objective novel ways and means whereby the stated result may be aptly accomplished.

In carrying out the desired principles of the inventive concept the preferred embodiment invokes the combination of a casement window frame having a window operiing, a casement window fitted in and normally closing said opening, and means swingably and slidabl'y mounting said window in the opening in said frame, whereby the swingably mounted portion of said window may be slid back and forth in said opening toward and from the adjacent frame member to provide a variable unobstructed space through which one may reach and thus have free access for washing the exterior surface of the window pane while at the same time remaining safely located within the room area.

More specifically stated, the invention appertains to an improved and practical casement window construction relying for novelty on the combination of a relatively stationary window frame embodying vertical members, an intervening horizontal top member and horizontal sill beneath said top member, one vertical member providing a jamb and the other vertical member providing a window stop, a horizontal track fixed to said top member, a complemental track mounted in said sill, a vertically'disposed carrier and hinging post'having its upper end' slidably keyed to said top track and having its'lower end slid'ably keyed in said complemental sill track, means separably 2,710,751 Patented June 14, 1955 interconnecting said post with said jamb, and an outwardly swinging casement window having one vertical edge hingedly mounted on said post, whereby said post and window may be unfastened and slid, as a unit, in a direction away from said jamb to provide an intervening unobstructed space between the jamb and post.

Then, too, novelty is predicated on the utilization of a traveling post which not only moves toward and from the cooperating vertical jamb of the window frame but is of a cross-section to cooperate with the window and also with a weather strip which is interposed between the post and the jamb to provide an effective weatherproofing association of parts when the window is closed, the post having at least one keeper slot and the weather I strip having a turn-button which cooperates with the slot,

making it possible to mechanically lock the post tightly against the weather strip to bring about the desired sealing coaction of parts.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the accompanying sheet of drawings wherein like numerals are employed to designate like parts throughout the views:

Figure 3 is a fragmentary elevational View taken on the vertical line 3-3 of Figure 1 looking in the direction of the arrows;

Figure 4 is an enlarged fragmentary sectional and elevational view with the window closed and showing the post locked against the jamb and intervening weather strip;

Figure 5 is a perspective View of the aforementioned post; and,

Figure -6 is a perspective view of the weather strip.

As is usual a window frame structure is set in opening means provided therefor in what is here broadly referred to as a building wall or other support 8. The frame structure comprises a vertical member or jamb 10 on one side which is vertically rabbeted at 12. Leading to the rabbet from the room side of the jamb, is a keyhole 14 to be hereinafter referred to. The opposite vertical frame member 16 (see Figure 2) is also rabbeted at 18 to provide a stop for the horizontally swinging casement window 20. The horizontal top frame member is denoted at 22 and, as shown in Figure 3, the underneath outer sideis rabbeted and a channel-shaped hanger track 24 is fixedly supported in the rabbet. The window sill, forming the remaining frame member, is horizontally disposed and denoted by the numeral 26 and the inner room side is denoted at 28 and the exterior apron side is denoted at 30. The central portion is longitudinally grooved to'accommodate a cylindrical track 32 opening by way of a slot through the top of said sill, the slot being shown at 34 in Figure 2. The outside trim board is denoted by the numeral 36 and the inside trim board is denoted at 38. A suitably shaped weather strip and adapter of appropriate metal is employed and this is denoted, as a unit, by the numeral 40 (see Figure 6). This is a triple-flange member. and the inwardly disposed fiange 42 is constructed to bear against the coacting. surface of the frame member 10 which now constitutes .the so-called jamb. The intermediate flange 44 and the complemental fiange 46 serve to conformably contact and face the surfaces of the aforementioned groove or rabbet 12.

There is a cut-out or notch at 48 communicating with the keyhole 14 and there is a cooperating keyhole 50 in the trim member 38 as seen in Figure 4 to accommodate an insertable and removable window turning key 52 which will be again referred to. The primary flange 42 is provided adjacent upper and lower ends with rotatably mounted turn-buttons 54 which serve as locking devices in a manner to be described.

The aforementioned sliding or traveling post is denoted by the numeral 56 and this too is appropriately shaped in cross-section and it is also a triple flange construction and includes an inwardly disposed flange 58 which abuts the flange 42, an intermediate flange 60 and an outwardly disposed complemental out flange 62 which latter two flanges abut and cooperate with the aforementioned flanges 44 and 46 respectively when the window is closed in the manner shown in Figure 4. The weather strip 40 is of course fixed to the jamb while the post 56 is slidably shifted toward and from it. The flange 58 has upper and lower elongated keeper slots 64 to accommodate the turn-buttons or keepers 54. By lining up the turn-buttons 54 with the slots 64, the two units, the weather strip 40 and post 56, may be locked together. This is accomplished by turning the buttons cross-wise in respect to the keeper slot in an obvious manner. The central web or flange 60 is provided at its lower end with a cylindrical fixedly attached assembling slide which may be conveniently referred to as a shoe 66. This is constructed to fit and reciprocate back and forth in the aforementioned cylindrical sill track 32. The same flange 60 is provided at its upper end with a hook shaped cleat 68 which as shown in Figure 3 is slidably interlocked with the cooperating channel track 24. It follows therefore, that the post 56 is slidable back and forth in the window frame opening and is capable of being locked to the jamb 10 by way of the weather strip 40 and fastenings just described. The cooperating pin connected hinging knuckles carried by the post and vertical hinging edge of the window respectively, serve to hingedly connect the window with the post so that the two travel as a unit. The knuckles on the post are denoted by the numerals 70 while those on the window are denoted at 72. The hinge plate or leaf on the window is denoted at 74 in Figure 4 and this serves to fixedly join a worm gear 76 thereto. The worm gear is a part of the so-called operator. As shown in Figure 4, a bearing sleeve 78 is fixed at 80 to the flange 62 in alignment with the worm gear. This serves to accommodate a worm shaft, the worm portion 82 of which is in mesh with the gear 76 as shown. A key accommodating socket 84 is provided in the shaft and lines up with the keyholes 14 and 50 to accommodate the aforementioned key 52. This is an insertable and removable key which serves to swing the window open from its anchorage position shown in Figure 3. The same key may be employed for swinging the window after the post and window have been adjusted to a window washing position. To accomplish this, the buttons 54 are released from the keeper slots 64. Now the post 56 is free from the Weatherstrip 40 and may he slid through the medium of the aforementioned tracks and shoes in a position from right to left, for example, in Figure 2. In fact, in Figure 2 the post is shown slid over to provide what has been referred to as a window washing space 86. In this figure the post is shown traveling in the direction of the arrow A. The window is partly open and may be swung in the direction of the arrows B so as to bring the exterior surface 88 to a position in convenient alignment with the space 86 whereby the person handling the window washing job may reach out through the space 86 and have access to the surface 88 for washing and cleaning. The worm gear and worm are of course operated to swing the casement window 20 in the direction of the arrow B through an arc to the desired position. As a matter of fact, the post 56 may be slid and shifted over into proximity to the window frame member 16 (not detailed) and the casement window may then be swung outside in through nearly an arcuate path of one-hundred and eighty degrees. Whatever position the window is swung to, the gearing serves to hold it steady so that the washing accomplishment may be readily taken care of.

It will be clear that when the window and post are locked to the jamb in the manner shown in Figure 4, the presence of the sliding feature of the post is unnoticed and the construction operates as any ordinary single hung horizontally swinging casement window construction. The essence of the invention is therefore in the separable traveling post supporting a hingedly mounted casement window permitting the Window to be swung outside in in proper relation to the space 86 for safe washing while the person handling the job remains within the area of the room.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
